If they are msd/holley 50 lb they will be a little bit of work to tune. You will have to adjust the injector flow rate table and the injector timing table (how fast the injectors open.

Im going to say that going with larger injectors is going to show some problems on the scans. I just dropped in 60lb injectors with no boost yet and the decels are causing major rich issues because the PCM cant command a low enough injector pulse width. To get around this I need to get a vacuum referenced fuel pressure regulator otherwise the rich decels are going to continue to happen which causes hesitation if I get on the gas during the rich decel.
